What portion of the cell forms part of the mitotic spindle during division?
The microtubules of the cytoskeleton form the mitotic spindle during cell division, along with associated proteins. These microtubules help separate the chromosomes during mitosis.
What act as focal points for the growth of the mitotic spindle?
Centrosomes are the main focal points for the growth of the mitotic spindle in eukaryotic cells. They contain pairs of centrioles that organize microtubules during cell division. The microtubules extend and form the spindle apparatus, which helps separate the chromosomes during mitosis.
What makes up the mitotic apparatus?
The mitotic apparatus is primarily composed of the mitotic spindle, which consists of microtubules that form a network to separate chromosomes during cell division. Key components include spindle fibers, which are organized by centrosomes, and motor proteins that help in the movement of chromosomes. Additionally, the mitotic apparatus includes kinetochores, which are protein structures on the chromosomes that attach to spindle fibers. Together, these components ensure accurate chromosome alignment and segregation during mitosis.
What phase does the spindle is formed?
The spindle is formed during the prophase stage of mitosis. Specifically, it begins to assemble during prophase as the centrosomes move to opposite poles of the cell, and microtubules extend from them to form the mitotic spindle. This structure is crucial for the segregation of chromosomes during cell division.
What would be the immediate consequence of destroying a cell's centrosomes?
Destroying a cell's centrosomes would lead to problems in organizing the microtubules during cell division, affecting the formation of the mitotic spindle. This could result in errors in chromosome segregation and cell division, leading to potential cell death or abnormal cell behavior.
How do microtubules form the mitotic spindle during cell division?
Microtubules form the mitotic spindle during cell division by organizing into a structure that helps separate chromosomes. The microtubules attach to the chromosomes and pull them apart, ensuring that each new cell receives the correct number of chromosomes.

What is the structure for spindle fibers?
During the metaphase of cell division, the spindle fibers radiate from the centrioles at the opposite poles of the cell. When the spindle fibers start to pull the chromosomes to opposite poles, this marks the anaphase of cell division.
What does the mitotic spindle form from?

One event occurring during prophase is?
The begining of the formation of the mitotic spindle-During prophase, the mitotic spindle begins to form.

This organelle found in animal cells functions in cell division and aids in spindle formation?
The organelle you are referring to is the centrosome. It contains a pair of centrioles and helps organize microtubules during cell division to form the mitotic spindle, which is essential for segregating chromosomes.
What is responsible for forming spindle during mitosis?
The centrioles within the cell form the mitotic spindle.
What phase of the eukaryotic cell cycle do microtubules arrange in preparation for mitosis?
they are produced by centrosome and they bind to the centromeres of sister chromatids during metaphase pulling each sister chromatid opposite sides so each daughter cell would contain one of them. mitotic division doesnt proceeds before microtubules bind to each centromere
What form a spindle shape structure of protein fibres on which the chromosomes move durung nuclear division?
The spindle shape structure of protein fibers that chromosomes move on during nuclear division is called the mitotic spindle. This structure is made up of microtubules that are responsible for segregating the chromosomes into the daughter cells during cell division.
